Made a setup package to install my vb.net appl but couldn't.

Hi,
I have made a setup package to install my vb.net2.0 appl .
when i made this package i included dotnet framework,mdoc28 and crystal reports.when i run this setup.exe file on the machine(running the same OS
XP pack 2) other than the one on which it was developed,it starts installing
dotnet framework but in the middle starts giving errors and couldn't install it and when it starts installing mdac, it says "this setup does not support installing on this OS" and stops.
I have developed this appl on .NET2.0 and when i made the setup package
i think VS has included the same version of .net and MDAC28.
Why is it happening?
Please help me out.
Regards!
